Instead of leds, you can connect any load through transistor keys. You can also connect multiple outputs (hole + led) to one transistor, for example, so that there are not 10 leds and 5, respectively, if the led (or their group) turns on signals from two adjacent outputs, the time of its glow will be 2 times more (signal time from one output + signal time from another). That's how i connected 5 led groups of different colors that flash in turn. I decided to share my idea. By the way, the ground on all outputs under the leds is common, so that the ground with the load connected through transistors can be connected by a common wire to the minus input of this signal generation board.
